Back pain

During the last two weeks, I worked non-stop for preparing lessons and marking assignments . Yesterday, my back pain and stiff neck came back and I realized perhaps I kept sitting in front of the computer for too long. My family doctor told me to move around or stretch my arms and legs every twenty minutes. It is a very good suggestion but how I can remember to do so unless a timer is put in front of me. To relieve pain and ache in my shoulders and back, I took pain-killers three times a day and applied Salonsip gel patches to the affected areas. It's so painful!! I even found it hard to stand straight this morning. I pray to get well soon as I need to give my second lecture on Monday. Keep my fingers crossed....
